TUBULAR LANTERN.

ciJIEICATZON forming part of Letters Patent No. 345,100, dated July 6,1886.

Application filed March 26, 1886. Serial No. 196,691. (No mmlol.)

To all whom it may concern.-

Be it known that we, ALFRED L. BARON and WILLIAM T. RUFER,eitizens ofthe United States, residing at Bellaire, in the county of Belmont andState of Ohio, have invented eertain new and useful Improvements inTubular Lanterns; and we do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

Our invention relates to tubular lanterns, and the improvements thereinare confined, principally, to a spring arrangedabove the bell or canopy,so as to exert an adjustable elastic pressure thereon, and a pair ofsprings attached to the guard and supporting the plate upon which theglobe rests. The purpose of these springs is to better adapt the lanternto receive globes of various lengths,to enable the globe to be moreeasily removed for cleaning, &c., and to enable the globe and itssupporting-plate to be raised for convenience in trimming and lightingthe wick; and the novelty lies in the peculiar construction andarrangement of these springs, all as will be more fully hereinafterdescribed, and pointed out in the claims. For a more perfectunderstanding of these parts in detail, and of their relation to theseveral parts of the lantern, attention is invited to the accompanyingdrawings, in which Figure 1 represents in side elevation a tubularlantern embodying our improvements; Fig. 2, a transverse section of thelantern looking down upon the plate which supports the globe, and Fig.3a detail of the upper spring and one of the lower springs.

Similar letters of reference denote corresponding parts in the severalviews.

The drawings show an ordinary tubular lantern, of which A denotes thebase; B, the airtubes; 0, the bell or canopy; D, the globe-supportingplate, and E an annular guard, all of which parts are about similar inevery respect to those commonly nsedin this class of lanterns, exceptingthe necessary adaptation of the globe-supporting plate D, which will behereinafter fully understood.

F is the upper spring,which is arranged beand acts as a guide to thehell or canopy,) and i have lateral play upon such cross-tube. Theeffect of a spring constructed and arranged in this way is, that insetting a globe of an unusual length the springs a (twill spread out atthe points where they are bent to form the clasp or loop p, and thusadjust themselves laterallyin proportion to the length of such globewith the same amount of adjustable pressure, but more widelydistributed.

G Gare the two lower springs, which are attached to the annular guard E,and support the globe -supporting plate D at opposite points upon'itsrim or flange. These springs are of like construction, and consist eachof a single wire bent at its center to fit partly aroundthe verticaltube B, as at 6, then coiled several times around the guard E uponopposite sides of the tube, as shown at e e, and then, with its twoarms, 0 0, carried out and passed through holes ff in the rim or flangeof the globe-supporting plate D, or through loops on the bottom of saidplate. These arms a c are bent up at the centers 6* c and are thenextended out in a horizontal line,and are bent at the ends into hooks e"a, between which points the plate D has movement in the act of raisingand lowering the globe or in removing and replacing a globe, as shown bydotted lines in Fig. 1. As represented by solid lines in said figure,when'a globe is in position, the plate D is held by the hooked ends ofthe springs G G in support upon the shoulder of the burner, and, asrepresented by dotted lines,when the globe is lifted-as, for instance,in trimming or lighting the wick or when it is removed-the said plate israised and held in a horizontal plane with the.,.,arms of-said springs.

The advantages asserted for our improvements are, exceeding strength andeheapness, combined with greater efficieneies.

What we claim, and desire to secure by Letters Patent, is.

1. The combination, with a tubular lantern provided with the side andcentral tubes and bell,as described, of the spring F, arranged beaspring arranged between the bell and the upper cross-tube, of theguardE, the globe,its su pporting-plate D, provided with holes f, and thesprings G G, each composed of spirals e e, wound around the guard, andtwo arms, 6 c projecting through said plate, substantially as described.

3. The combination, with a tubular lantern, of the guard E, thesupporting-plate D, and the springs G G, each composed of spirals e e,wound around the guard, and two arms, 0" c, with bends e d, and hookedends 6 e, substantially as and for the purposes described.

4. The combination,with atubular lantern, of the bell, the globe, thesupporting-plate, the guard, the spring F, arranged above the bell andcomposed of a single wire bent into two C-springs united byaspring-clasparound the central tube, and the springsG G, con nected to the guard andto the plate, and composed eaoh of two spirals, e e, and two arms, 0"e", substantially as described.

, In testimony whereof we afiix our signatures in presence of twowitnesses.
